[Acid phosphatase in the nerve tissue exposed to local vibration]

The results of examinations for acid phosphatase in the spinal neurons of cats treated by vibration are presented. The animals were subjected to various periods of vibration with parameters of 20 Hz frequency and 2 mm amplitude. The activity of acid phosphatase in the nervous tissue was found to depend upon the duration of vibration: after a short-term treatment the activity of the enzyme was reduced insignificantly, after a long-term treatment a sharp reduction of the enzyme activity was observed in most cells.
